Superfluid Turbulence and Pulsar Glitch Statistics
Experimental evidence is reviewed for the existence of superfluid turbulence in a differentially rotating, spherical shell at high Reynolds numbers (Re > ∼ 10 ), such as the outer core of a neutron star. It is shown that torque variability increases with Re, suggesting that glitch activity in radio pulsars may be a function of Re as well. The Re distribution of the 67 glitching radio pulsars wi...
متن کاملPulsar glitch substructure and pulsar interiors
Pulsar timing at the Mt Pleasant observatory focused on Vela, which could be tracked for 18 hours of the day. These nearly continuous timing records extend over 24 years allowing a great insight into details of timing noise, micro glitches and other more exotic effects. It has been found that the spin up for the Vela pulsar occurs instantaneously to within the uncertainties of the data. The pot...
متن کاملThe effect of superfluid hydrodynamics on pulsar glitch sizes and waiting times
Pulsar glitches, sudden jumps in frequency observed in many radio pulsars, may be the macroscopic manifestation of superfluid vortex avalanches on the microscopic scale. Small scale quantum mechanical simulations of vortex motion in a decelerating container have shown that such events are possible and predict power-law distributions for the size of the events, and exponential distributions for ...
متن کاملPulsar Astrophysics : the Glitch Phenomenon
Received Day Month Year Revised Day Month Year We briefly discuss a handful of topics in pulsar astrophysics, first some general well-known features, then an overview of the glitch phenomenon and the sort of information gathered about the internal structure and dynamics, and finally the quandary posed by the precession of PSR B1828-11 a very important clue pointing towards a novel paradigm for ...
متن کاملA Frequency Glitch in an Accreting Pulsar
Frequency glitches have been observed so far only in radio pulsars and anomalous X-ray pulsars. Here we present evidence of a glitch in a neutron star accreting from a Be companion. The transient KS 1947+300 reappeared in 2000 October as a moderately strong X-ray source that exhibited 18.7 s pulsations, leading to an identification with the BATSE source GRO J1948+32, last detected in 1994. We h...
